Abstract

The invention relates to fiber products, in particular to a nanosilver antibacterial fiber preparation method. The method includes steps: (1) preparing plant charcoal micropowder; (2) dispersing silver powder into organic solvent, ultrasonically treating, adding titanium dioxide and plant charcoal micropowder, and stirring to obtain a mixture; (3) adding a silane coupling agent, a surfactant and adispersing agent, well mixing, adding into an extruder along with polyester through a loss-in-weight feeder, and performing melt mixing and spinning to obtain antibacterial fibers, wherein the silverpowder refers to a mixture of nano silver powder and micro silver powder. The nanosilver antibacterial fiber preparation method is simple and convenient, and convenience in realization of large-scaleindustrial production is achieved. The silver powder coated with organic solvent is attached in porous structures of plant charcoal particles, attachment effects and stability effects in polyester fibers are improved, and long-acting antibacterial effects are guaranteed.

Description

Technical field [0001] The invention relates to fiber products, in particular to a method for preparing nano silver antibacterial fibers. Background technique [0002] my country has the world's largest consumer group, and the consumption concept of home textile products is gradually changing. With the improvement of people's living standards and the development of technology, the huge consumption potential of home textile market is being released. In a narrow sense, textiles refer to the two series of woven fabrics and knitted fabrics, and chemical fiber spinning products are gradually entering people's field of vision. [0003] Functional textiles were first proposed by German scientists in the 1980s and quickly responded in developed countries. Countries all over the world have invested a lot of money in research and development. People all want to use fiber products with antimicrobial activity to protect users. Protect it from external bacteria and other microorganisms. In th...
